Bests & Worsts Reviews from Amazon

I bought this Uspeed USB 3.0 PCI-E card from Amazon in order to have the latest and much faster USB on my existing computers. This is a very cost effective and fairly simple way to increase your USB speeds by a factor of 10 over USB 2.0(if you have USB 3.0 capable devices). If you're transferring large files or cloning disks via USB docks this is the way to go. PROS: It's less expensive than most similar items and works perfectly when installed correctly. Physical installation is simple and obvious - be sure to insert the card fully into the appropriate slot and then attach one of the Molex 4-pin connectors from your power supply. CONS: I bought three of these for various household computers (different brands and specs) and none of the driver installation disks worked with any of the computers. The Uspeed website (USPEED.CO) is a frustrating mish-mash of broken links, confusing navigation, and missing drivers. HELPFUL HINTS: Try installing the driver disk and it may work. If not, you can try navigating into the Device Manager in Windows and tell Windows to try and find the driver (apparently works for some, but didn't work for me). Or you can save yourself some grief and go straight to VIA for the driver. What you want is VIA's xhci (extensible host controller interface) USB 3.0 driver. Currently the driver is named VL810 Superspeed USB Hub Controller Firmware 0.89 - Released July 22, 2011. Don't bother trying the Intel xhci driver, it's easier to find but won't work. UPDATE: The latest update to the driver is now version 0.95. VIA says that this update "Resolved issue with Intel USB 3.0 Host where devices were occasionally not properly re-enumerated after resuming from S3/S4, warm-boot, or cold boot." (I did not have that issue with version 0.89) UPDATE II: Please read the comments section attached to this review as another helpful user has turned up some interesting information. CURRENT VIA URL: (Deleted by Amazon) WARNING: If you do a Google search for the driver most of your hits are going to be from outfits trying to con you into downloading their proprietary driver-update software. Don't do it, your computer will end up slow and cluttered with spam. Get the driver directly from VIA. UPDATE III: Again, please read the comments section. Many users have been very helpful with reporting their experiences, tips, & tricks.
